I always went to bed at the same time, but DS would be well asleep by then because I'd have done my evening things with him in the sling. We don't watch TV, but for me it would be internet (BB!) that I would want to do. Cos he was so small it didn't matter that he was still on me.
As he got older, he would stay asleep on his own in the bed and when he stirred I'd jump in.
Put it this way, knowing how little this time lasts, I was happy to have him on me because I knew it wouldn't feel like too long before I'd have to put him down first (with him getting bigger and more cumbersome to carry for more than brief periods etc)
